I've been watching MMA for a long time. Everything Possum said is correct, and everyone knows I don't agree with him often.
RR isn't going to learn to box in a few months which means her game plan isn't going to be much different than the first fight. It's widely known that her coach was basically a nobody before she showed up at his gym. He's no Tri-Star or Alpha Male, if you even know who they are.
Her only hope is switching camps, setting the celebrity stuff aside and getting straight to the gym in an attempt to improve every aspect of her fight game. Remember, she was tooled at her OWN game as well as the stand up.
I'm not saying she can't improve but it's not going to happen over night. She's been fighting smaller, less skilled fighters since she got into MMA and underestimated what Holly would bring to the cage. Had she been with a real fight camp the coaches may have been able to strategize around it. Instead, she thought since she beat Bethe on the feet that she was better than she really was.
In closing, Corgster and most others on this site are MMA noobs and are blinded by their fanboyism. They're not looking at it subjectively from a neutral stand point.
